About Mahi Mahi Fishing in Charleston
Also called Dolphin or Dorado. Stunningly beautiful and acrobatic. Excellent eating.
Mahi Mahi — also called Dolphin or Dorado — are the most brilliantly colored fish in the ocean. Their iridescent body shimmers with electric blues, greens, and golds that literally change before your eyes. Males (called "bulls") develop a prominent flat forehead, while females ("cows") have a more rounded head profile. These fast-growing pelagic fish are found in blue water near floating debris, weed lines, and current edges. They are acrobatic fighters that tailwalk across the surface and make spectacular aerial leaps.
Scientific name: Coryphaena hippurus

How to Catch Mahi Mahi in Charleston
Techniques & Bait
Trolling ballyhoo rigged with colorful duster/lure combinations along weed lines, current edges, and near floating debris is the classic technique. Once a school is located, stop the boat and pitch live pilchards, cut ballyhoo, or small live baits to the school — mahi travel in groups and multiple hookups are common. Casting light jigs, spoons, or fly-rod streamers to fish visible near floating objects is incredibly exciting. Keep one fish in the water next to the boat to hold the school in place while catching others.
Recommended Tackle
Medium spinning or conventional rod (6'6"-7 ft), 4000-5000 reel, 20-30 lb braid, 30-40 lb fluorocarbon leader. For trolling: 20-30 lb class conventional rigs. Mahi have sandpaper-like mouths — fluorocarbon leader works fine (no wire needed).
Best Deep Sea Fishing Fishing Spots in Charleston
Top spots where local captains target mahi mahi and other deep sea fishing species.
The Charleston Bump (Gulf Stream)
The Charleston Bump is a dramatic underwater plateau that deflects the Gulf Stream eastward and creates one of the most unique offshore fishing environments on the Atlantic coast. The upwelling generated by the Bump concentrates swordfish, yellowfin tuna, wahoo, mahi-mahi, and blue marlin in remarkable densities. Charleston is internationally recognized as a premier swordfish port largely because of this geological feature.
The Snowy Wreck
The Snowy Wreck is a well-known artificial reef and sunken vessel lying in deep water offshore of Charleston, attracting large concentrations of snowy grouper, tilefish, and other deepwater bottom dwellers. Amberjack and barracuda hold above the wreck structure, while occasional wahoo and king mackerel pass through the area. It is a favorite destination for anglers targeting deep-drop species on full-day and overnight trips.
The 60-Mile Grounds
The 60-Mile Grounds refer to a productive stretch of ledges and hard bottom along the continental shelf edge approximately 60 miles southeast of Charleston. Vermilion snapper, triggerfish, amberjack, gag grouper, and scamp are pulled from the deep structure, while the proximity to the Gulf Stream brings pelagic action above the reef. This area serves as a transition zone between bottom fishing and bluewater trolling.
The Georgetown Shelf Break
The shelf break northeast of Charleston drops from approximately 100 feet to over 300 feet in a short distance, creating a wall of structure that holds an incredible diversity of deepwater species. Warsaw grouper, snowy grouper, tilefish, and golden crab are targeted with deep-drop rigs along the ledges. The break also produces quality yellowfin tuna and wahoo when the Gulf Stream pushes close.
